Turks and Caicos is an archipelago of 40 low-lying coral islands in the Atlantic Ocean, southeast of the Bahamas. The island of Providenciales, known as Provo, is home to expansive Grace Bay Beach, with luxury resorts, shops and restaurants. Scuba-diving sites include a 14-mile barrier reef on Provo’s north shore and a dramatic 2,134m underwater wall off Grand Turk island.
